CRTS II type double-block type non-fragment rail bed board construction method

The invention relates to the technical field of ballastless track construction, in particular to a CRTS II-type double-block ballastless-track ballast board construction method, which solves the problem of respective different disadvantages existing in the prior various ballastless track construction methods. The construction method comprises the following processes of constructing ballastless track supporting layers, installing supporting feet, installing steel formwork tracks, laying ballast board steel reinforcement, pouring ballast board concrete, installing sleepers, plastering, maintaining and the like. The construction method utilizes complete sets of equipment for construction, has the characteristics of high mechanization degree, high construction efficiency, short construction period, is advanced in measurement technique, strict in requirements on measurement standards, high in precision, fast and convenient in field operation and capable of sectioned laying, and has good flexibility during the arrangement for the construction sequence of every construction section. Practice proves that the construction method is relatively mature, and meets the requirement of passenger dedicated line acceptance standard on the quality of finished ballastless tracks; in addition, compared with other types of ballastless tracks, the construction method has the advantages of lower construction cost, investment reduction and especially remarkable comprehensive economic benefit.
